Activities

Unless otherwise noted, the activities were developed by Deborah Scherrer.
A few were designed in collaboration
with a team of educators through a project of the Center for Extreme Ultraviolet
Astrophysics group at the University of California, Berkeley.
The team included Sherry Johnson, Jerry Abad, Tom Wright,
Rey Urbach, and the Center Coordinator, Deborah Scherrer.

Many images in the website are from the SOlar and Heliospheric Observatory (SOHO).
SOHO is a mission of international cooperation between ESA (the European
Space Agency) and NASA.

Funding Agencies

Development of the Solar Center has been supported financially at
Stanford University by the National Aeronautics and Space
Administration (NASA) through Grant NAG5-3077.
This grant supports Mission Operations and
Data Analysis of the Solar Oscillations Investigation Michelson Doppler
Imager instrument on the SOlar and Heliospheric Observatory (SOHO).

Portions of the work were also supported by the National Science Foundation
through grant ATM-9400298 to Stanford University.

Imagery credits for the Solar Art section and the Medicine Wheel section are given along
with the imagery on the various pages.

EIT instrument on the SOHO spacecraft. The image of Stanford
was taken by Phillip Rittmuller, an engineer at the Jet Propulsion
Laboratory, Pasadena, CA. The combination image of a solar flare
with an oscillation model superimposed was developed by Bala
The NASA and NSF logos belong to their respective agencies.

Many of the solar images were produced by the various
instrument teams on the SOHO spacecraft.
Use of SOHO images for public education efforts and non-commercial
purposes is strongly encouraged and requires
no expressed authorization. It is requested, however, that any
such use properly attributes the source of the images as:
"Courtesy of SOHO/(instrument name) consortium.
SOHO is a project of international cooperation
between ESA and NASA."

The magnetograms are from the MDI instrument on the SOHO
spacecraft. The MDI instrument was designed and built by
the Solar Observatories Group at Stanford University
and the Lockheed-Martin Palo Alto Research Laboratory.
SOI-MDI images are available for reproduction for educational, news, and
informational purposes, as long as the following citation is given:
"Image(s) courtesy of the SOHO/SOI-MDI project of the Stanford Lockheed
Institute for Space Research. SOHO is a project of international
cooperation between ESA and NASA."

The solar x-ray images are from the Yohkoh mission of ISAS, Japan.
The Yohkoh Soft X-ray Telescope is a collaborative
project of the Lockheed Palo Alto Research
Laboratory, the National Astronomical Observatory of Japan, and the
University of Tokyo, supported by NASA and ISAS.

The black hole signature spectrum and description were created with
support to Space Telescope Science Institute,
operated by the Association of Universities for Research in Astronomy,
Inc., from NASA contract
NAS5-26555, and are reproduced with permission from AURA/STScI.
Digital renditions of images produced by AURA/STScI are
obtainable royalty-free for educational and non-profit use.

The solar eclipse icon is from the High Altitude Observatory, NCAR,
Boulder, CO.

The raven image on some of the Native American folklore pages is actually a head-dress.
The body is leather (or some kind of
fabric) and serves as a hat. The wings fold down over the wearer's ears, and
the tail folds back over one's neck. The beak protrudes from one's
forehead.
The artifact was produced by the Haida tribe of the Pacific Northwest. It is
owned by the Department of Anthropology, National Museum of Natural History, Smithsonian
Institutes. Washington D.C. The photographer is Don Eiler.
